Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543094, here are decompositions:

103 + 31542991 = 31543094
127 + 31542967 = 31543094
151 + 31542943 = 31543094
157 + 31542937 = 31543094
283 + 31542811 = 31543094
307 + 31542787 = 31543094
367 + 31542727 = 31543094
397 + 31542697 = 31543094

Showing the first eight; more decompositions exist.
